Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application, and it is obvious that the described embodiments are some but not all of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The term of the present application is to be interpreted:
the main speaking device comprises: in multicast or multicast service, the device is authorized to act as a main speaker for sending data packets to the data forwarding server so that the data forwarding server sends the received data packets to the receiving device.
The monitoring equipment: and the device receives the data packet forwarded by the data forwarding server from the talkback device in the multicast or multicast service.
Downlink multicast channel: and in a multicast channel between the data forwarding server and the monitoring equipment, the data forwarding server can send the data packet from the main speaking equipment to the monitoring equipment through the multicast channel. Illustratively, if the listening devices are A, B and C, the channel for the data forwarding server to send data from the intercom device to both listening devices A, B and C is a multicast channel.
Unicast channel: this application refers to the channel between the data forwarding server and one listening device. Illustratively, if the listening devices are A, B and C, the channel through which the data forwarding server sends data from the intercom device to listening device a alone is a unicast channel.
Sequence number of packet: the talker device transmits packets to the listener device, each packet having a Sequence Number (SEQ). The sequence numbers of the data packets continuously sent by the master device to the listener devices are continuous. Illustratively, if a user corresponding to the intercom device speaks a session, the intercom device generates a plurality of data packets corresponding to the session and sends the data packets to the listening device, where the sequence numbers of the data packets corresponding to the session are 1, 2, and 3, for example.
Identification of the packet's talker: the source (SSRC) of the data packet, i.e. the identity of the speaking device that sent the data packet. For example, if a data packet received by the listening device is from the intercom device a, the SSRC corresponding to the data packet is the intercom device a.
Packet loss: after receiving the data packet from the main speaking device, the monitoring device determines that packet loss occurs in the data packet if the sequence number of the data packet is discontinuous. Illustratively, the data packets sent by the intercom device to the listening device should be 1, 2, 3, and 4, but the data packets received by the listening device are 1, 2, and 4 due to the poor network environment where the intercom device is located or due to other reasons, the data packet 3 is lost in the received data packet.
In order to more clearly explain the data processing method in the present application, a data processing method in the related art is first explained below.
Fig. 1 is a schematic view of a data processing scenario in a cluster service provided in the prior art. As shown in fig. 1, the scenario includes: a main intercom device 10, a data forwarding server 20, a listening device 30, a listening device 40 and a listening device 50. It should be understood that fig. 1 exemplarily shows 3 listening devices, but other numbers are of course possible. The channel for the user to transmit the data packet between the data forwarding server 20 and the monitoring device 30 is a multicast channel a, the channel for the user to transmit the data packet between the data forwarding server 20 and the monitoring device 40 is a multicast channel b, and the channel for the user to transmit the data packet between the data forwarding server 20 and the monitoring device 50 is a multicast channel c.
It will be appreciated that a plurality of listening devices may be included in each of listening device 30, listening device 40 and listening device 50. Fig. 1 exemplarily shows that listening devices B and C are included in listening device 30, listening devices D and E are included in listening device 40, and listening devices F and G are included in listening device 50. Correspondingly, the intercom device 10 may transmit the data packet to the monitoring devices B and C through the multicast channel a, the intercom device 10 may transmit the data packet to the monitoring devices D and E through the multicast channel B, and the intercom device 10 may transmit the data packet to the monitoring devices F and G through the multicast channel C.
In the scenario shown in fig. 1, if a packet received by the monitoring device is lost. One possible implementation manner provided in the prior art is as follows: the monitoring device that has lost the packet will send a packet loss retransmission request to the data forwarding server 20, and send the sequence number of the lost data packet to the data forwarding server 20. After receiving the packet loss reissue request sent by the monitoring device, the data forwarding server 20 establishes a unicast channel with the monitoring device to resend the lost data packet. Alternatively, the lost packet may be a packet requested by the data forwarding server 20 from the intercom device 10, or may be a packet stored in the data forwarding server 20.
Fig. 2 is a schematic view of a scenario when a packet is lost in a cluster service provided in the prior art. As shown in fig. 2, if data packets received by the monitoring devices B and C are lost, the monitoring devices B and C both send a packet loss complementary transmission request to the forwarding server 20, and after receiving the packet loss complementary transmission request sent by the monitoring devices B and C, the data forwarding server 20 establishes unicast channels, such as unicast channels d and e, with the monitoring devices B and C to send the lost data packets. The method in the prior art needs to additionally establish a unicast channel, and occupies a large amount of transmission bandwidth. The number of the monitoring devices with packet loss shown in fig. 2 is 2, and when a large number of data packets received by the monitoring devices are all packet loss, a large number of additional unicast channels need to be established between the data forwarding server 20 and the monitoring devices, so that a larger amount of transmission bandwidth is occupied, and the progress of other services is affected.
In the scenario shown in fig. 1, if a packet received by the monitoring device is lost. Another possible implementation provided in the prior art is packet loss compensation. When the sequence number of the data packet received by the data forwarding server is discontinuous, a plurality of silent data packets can be compensated, and then the silent data packets are sent to the monitoring equipment. For example, suppose a packet is lost, sequence numbers of the packets received by the receiving end are 1 and 3, and a packet with sequence number 2 is lost in the middle. When compensating the silent audio frame, the data forwarding server adds a silent data packet between sequence numbers 1 and 3 of the data packets, thereby ensuring the continuity of the sequence numbers of the data packets received by the monitoring equipment.
However, this method has some problems, firstly, the complexity is increased, an algorithm for generating a silent data packet needs to be implemented in the data forwarding server, and secondly, the time delay is increased, because a certain amount of packet data must be buffered to compensate for the silent data packet, and then it can be determined which packet loss exists in the received data packet, and further, the silent data packet can be compensated.
In order to solve the above problems, the present application provides a data processing method, in a transmission process of a downlink data packet, by setting a monitoring device between a data forwarding server and the monitoring device, the monitoring device can modify a serial number of the data packet that has a packet loss, so that the serial number of the data packet received by the monitoring device is continuous, the monitoring device is prevented from sensing a packet loss behavior of the data packet, and further, a problem that an extra channel is established to occupy a large amount of transmission bandwidth is avoided.
It should be understood that the scene diagram shown in fig. 1 is also a scene diagram to which the data processing method provided in the present application is applicable.
The intercom device and the listening device in the present application may include, but are not limited to, a mobile terminal or a fixed terminal. The mobile terminal devices include, but are not limited to, a mobile phone, a Personal Digital Assistant (PDA), a tablet computer, a portable device (e.g., a portable computer, a pocket computer, or a handheld computer), and the like. Fixed terminals include, but are not limited to, desktop computers and the like.
Fig. 3 is a first schematic flow chart of a data processing method provided in the present application. The execution entity of the method flow shown in fig. 3 may be a data processing device, which may be implemented by any software and/or hardware. As shown in fig. 3, the data processing method provided in this embodiment may include:
s301, the monitoring device receives a first data packet from the talkback device forwarded by the data forwarding server.
In the multicast service, the intercom device sends the data packet to the data forwarding server, and the data forwarding server sends the received data packet to the monitoring device. Correspondingly, the listening device may receive the data packet from the intercom device forwarded by the data forwarding server.
When multicast service is performed between the talkback device and the monitoring device, the talkback device may send a plurality of data packets to the monitoring device. It should be understood that, in this embodiment, the data packet from the intercom device forwarded by the data forwarding server currently received by the listening device is taken as the first data packet.
Optionally, if the multicast service in this embodiment is a voice multicast service, the corresponding first data packet may be an audio real-time transport protocol RTP data packet.
S302, if the sequence numbers of the first data packet and the second data packet are not consecutive, the monitoring device modifies the sequence number of the first data packet so that the sequence numbers of the first data packet and the second data packet are consecutive, and the second data packet is a previous data packet received by the monitoring device.
The first data packet received by the listening device carries a sequence number of the data packet, or the first data packet may be marked with a corresponding sequence number. The listening device may determine a sequence number of the first data packet after receiving the first data packet.
In this embodiment, after receiving the first data packet, the monitoring device may compare and determine the sequence number of the last data packet, that is, the sequence number of the second data packet, where if the sequence numbers of the first data packet and the second data packet are not consecutive, it is proved that packet loss occurs between the first data packet and the second data packet.
Optionally, if the multicast service in this embodiment is a voice multicast service, the corresponding first data packet may be an audio real-time transport protocol RTP data packet.
In this embodiment, to avoid the problem that a large number of unicast channels are established due to packet loss and a large number of transmission bandwidths are occupied, the sequence number of the first data packet with a discontinuous sequence number is modified, so that the sequence numbers of the first data packet and the second data packet are continuous.
In this embodiment, when packet loss occurs, the sequence number of the received data packet may be modified, so that the sequence number of the data packet received by the monitoring device is continuous, that is, the monitoring device does not sense the occurrence of packet loss, and further, the problem that a large amount of transmission broadband is occupied due to the establishment of a large number of unicast channels due to packet loss is avoided.
In addition, the data transmission method provided in this embodiment is to determine whether the sequence number of the data packet is consecutive to the sequence number of the previous data packet when the monitoring device receives each data packet, and modify the sequence number of the data packet to a sequence number consecutive to the sequence number of the previous data packet if the sequence number is not consecutive, so as to avoid the problems that a certain amount of packet data needs to be buffered and the delay of receiving the data packet by the monitoring device in the prior art is increased.
Illustratively, if the sequence number of a first data packet received by the snooping device is 3 and the sequence number of a second data packet received last is 1, it is determined that the sequence numbers of the first data packet and the second data packet are not consecutive, the snooping device modifies the sequence number of the first data packet, for example, modifies the sequence number of the first data packet to 2, so that the modified sequence numbers of the first data packet and the second data packet are consecutive.
The data processing method provided in the present embodiment includes: the monitoring equipment receives a first data packet from the talkback equipment forwarded by the data forwarding server; if the sequence numbers of the first data packet and the second data packet are not continuous, the monitoring equipment modifies the sequence number of the first data packet so as to ensure that the sequence numbers of the first data packet and the second data packet are continuous, and the second data packet is the last data packet received by the monitoring equipment; and the monitoring equipment sends the first data packet with the modified serial number to the receiving equipment. In the data processing method provided by the application, in the transmission process of the downlink data packet, the monitoring equipment can modify the serial number of the data packet with the packet loss, so that the serial number of the data packet received by the receiving equipment is continuous, the receiving equipment is prevented from sensing the packet loss behavior of the data packet, and the problem that a large amount of transmission bandwidth is occupied by additionally establishing a channel is avoided.
On the basis of the above embodiments, the data processing method provided by the present application is further described below with reference to fig. 4. Fig. 4 is a schematic flowchart of a second data processing method provided in the present application, and as shown in fig. 4, the data processing method provided in this embodiment may include:
s401, the monitoring device receives a first data packet from the talkback device forwarded by the data forwarding server.
S402, if the sequence numbers of the first data packet and the second data packet are not continuous, the monitoring equipment modifies the sequence number of the first data packet so as to make the sequence numbers of the first data packet and the second data packet continuous.
And S403, if the identification of the talkback device of the first data packet is different from the identification of the talkback device of the second data packet, the monitoring device modifies the identification of the talkback device of the first data packet into the identification of the talkback device of the second data packet.
It should be understood that the implementation manners in S401 to S402 in this embodiment may refer to the relevant descriptions in S301 to S302 in the above embodiments, and are not limited herein. It should be noted that, in this embodiment, the execution sequence of S403 and S402 is not limited, and the two operations may also be executed simultaneously. The following specifically describes the embodiment in S403.
The data packet received by the listening device and sent from the intercom device carries an identifier (SSRC) of the intercom device. In the above S403, correspondingly, the first data packet may carry the identifier of the intercom device of the first data packet.
In a possible implementation manner, the scenarios corresponding to the implementation manners in S401 to S402 in this embodiment are: the listener device determines that the identity of the talker for the first packet is the same as the identity of the talker for the second packet.
In this embodiment, if the monitoring device determines that the identifier of the intercom device of the first data packet is the same as the identifier of the intercom device of the second data packet, that is, it determines that the intercom device has not switched, the monitoring device may modify the sequence number of the first data packet when the sequence numbers of the first data packet and the second data packet are not consecutive. In this scenario, since the master device is not switched, the monitoring terminal does not perceive packet loss by modifying the sequence number of the first data packet so that the sequence numbers of the first data packet and the second data packet are consecutive.
In a possible implementation manner, if the identifier of the intercom device of the first data packet is different from the identifier of the intercom device of the second data packet, that is, the intercom device in the multicast service is switched, that is, the intercom device of the first data packet is different from the intercom device of the second data packet. In this scenario, the monitoring device can recognize the switching of the main speaking device, and if the serial numbers of the data packets sent by the same main speaking device are modified to be continuous, although the monitoring terminal cannot sense the packet loss when receiving the data packets of the same main speaking device, the monitoring terminal can sense the packet loss when receiving the data packets of different main speaking devices, and further, the problem of additionally establishing a unicast channel can be solved.
For example, if the identification of the intercom device of the first packet is different from the identification of the intercom device of the second packet, the intercom device that sends the first packet is correspondingly different from the intercom device that sends the second packet. For example, the data packets sent by the talkback device a to the listening device have sequence numbers of 1, 2 and 5, and the data packets sent by the talkback device a' to the listening device have sequence numbers of 2, 3 and 5. When the monitoring equipment receives a data packet sent by the talkback equipment A, the serial number of the data packet can be modified into 1, 2 and 3; correspondingly, when the monitoring device receives the data packet sent by the talkback device a ', because the change of the talkback device can be sensed, the serial number of the data packet can be modified to 2, 3 and 5, but the modified serial number of the data packet is repeated with the modified serial number of the data packet sent by the talkback device a, and the monitoring device may drop the data packet sent by the talkback device a', which has the modified serial number of 2 and 3.
In order to avoid the above situation, in this embodiment, after the snooping device receives the first data packet, the identifier of the intercom device of the first data packet may be compared with the identifier of the intercom device of the second data packet received last. If the identification of the intercom device of the first data packet is different from the identification of the intercom device of the second data packet, it is determined that the intercom device is switched after receiving the second data packet, that is, the intercom device of the first data packet is different from the intercom device of the second data packet.
Correspondingly, if the identification of the talkback device of the first data packet is different from the identification of the talkback device of the second data packet, the monitoring device modifies the identification of the talkback device of the first data packet into the identification of the talkback device of the second data packet, so that the monitoring device does not sense the identification of the talkback device of the received data packet and only modifies the serial number of the data packet.
As shown in the above example, the data packets sent by the intercom device a to the listening device have sequence numbers of 1, 2 and 5, and the data packets sent by the intercom device a' to the listening device have sequence numbers of 2, 3 and 5. The data packets with sequence numbers of 1, 2 and 5 sent by the talkback device a to the monitoring device carry the identifier of the talkback device a, such as "a", and the data packets with sequence numbers of 2, 3 and 5 sent by the talkback device a ' to the monitoring device carry the identifier of the talkback device a ', such as "a '". Correspondingly, in this embodiment, the identification of the intercom device may be "a '", and the identifications of the intercom devices with the serial numbers of 2, 3 and 5 packets may be modified from "a'" to "a".
Correspondingly, according to the embodiment in S402 in this embodiment, the sequence numbers of the packets with sequence numbers 1, 2, and 5 may be modified to 1, 2, and 3, respectively, and the sequence numbers of the packets with sequence numbers 2, 3, and 5 may be modified to 4, 5, and 6, so that the sequence numbers of the packets are kept continuous in the scenario of whether the intercom device is switched or not.
The first table shows a correspondence table before and after modification of the serial number of the data packet received by the listening device, the identification of the intercom device.

In this embodiment, if the identifier of the intercom device of the first data packet is different from the identifier of the intercom device of the second data packet, the monitoring device modifies the identifier of the intercom device of the first data packet into the identifier of the intercom device of the second data packet, and if the serial numbers of the first data packet and the second data packet are not consecutive, the monitoring device modifies the serial number of the first data packet so that the serial numbers of the first data packet and the second data packet are consecutive, and the second data packet is the last data packet received by the monitoring device. The data processing method provided in this embodiment can avoid the problem that the monitoring device loses packets of data packets corresponding to different pieces of intercom equipment after the serial number of the first data packet is modified when the intercom equipment is switched.

Optionally, the processing module 502 is further configured to modify the identifier of the intercom device of the first data packet into the identifier of the intercom device of the second data packet if the identifier of the intercom device of the first data packet is different from the identifier of the intercom device of the second data packet.
Optionally, before the processing module 502 modifies the sequence number of the first data packet when the sequence numbers of the first data packet and the second data packet are not consecutive, the processing module 502 is further configured to determine that the identifier of the intercom device of the first data packet is the same as the identifier of the intercom device of the second data packet.
